A 3D printing filament connector

Abstract

This utility model relates to the technical field of 3D printing connector equipment and discloses a 3D printing consumable connector, including a support frame with a base installed at the bottom. Both sides of the support frame have through-tubes, and the through-tubes are rotatably connected to the support frame via bearings. This utility model allows the conical sleeve and conical ring cutter to rotate during the conveying process after the consumable filament is connected, thereby enabling the conical ring cutter to quickly and effectively remove uneven areas at the connection, ensuring a smooth connection. This solves the problem in existing technologies where, during the conveying process of the consumable filament, the hollow conical cutter directly contacts the uneven areas at the connection, simply using compression to remove the uneven areas. The low friction between the hollow conical cutter and the uneven areas makes it difficult for the cutter to apply sufficient and effective cutting force, resulting in a slow removal process and an inability to quickly smooth the uneven areas.

Description

Technical Field

[0001] This utility model belongs to the technical field of 3D printing connector equipment, specifically, it relates to a 3D printing consumable connector. Background Technology

[0002] In the field of 3D printing, a filament connector is a device used to connect two 3D printing materials (usually molten plastic filaments) together to achieve a seamless transition of materials during the printing process. This device typically uses heat fusion or other methods to bond the two materials together to ensure a continuous supply of material during printing and to make the printing results smoother and more continuous.

[0003] According to Chinese Patent Publication No. CN221756874U, a 3D printing filament connector is disclosed. This connector utilizes an external threaded ring block on the filament tube. The fastening ring block can be twisted to connect with the external threaded ring block and fit snugly against the inner side of the support base. During connection, a limiting ring rotates into a limiting ring groove to maintain stability after connection and simultaneously aligns with the inner cone block. This allows the filament thread to pass through the filament tube and protrude into the hollow cone cutter. After the two sets of exposed filament threads are bonded together using a hot-melt tool, any unevenness at the connection point during filament thread movement is addressed by the hollow cone cutter. The process of removing uneven areas by hand after bonding ensures a smooth joint and avoids uneven removal caused by manual cutting. This method is time-saving and labor-saving, and can also remove other irregular parts of the consumables during transportation, improving the overall quality. When not in use, the fastening ring can be twisted off for easy replacement after long-term use. Waste material during removal will fall directly into the receiving groove under the support base for centralized disposal, keeping the site clean. The multiple sets of mounting holes facilitate the installation of the support base and improve the overall stability of use.

[0004] However, in the above-mentioned technical solutions, during the feeding process of the consumable filament, the hollow cone cutter directly contacts the uneven area at the connection of the consumable filament, and the uneven area is removed simply by squeezing. The friction between the hollow cone cutter and the uneven area is small, and the cutter is unable to apply sufficient and effective cutting force to the uneven part, resulting in a slow removal process and an inability to quickly smooth the uneven area. Therefore, we propose a 3D printing consumable connector. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A 3D printing consumable connector includes a support frame with a base mounted at the bottom. Two conduits extend through both sides of the support frame and are rotatably connected to the support frame via bearings. Conical sleeves are fitted onto opposite ends of the two conduits, with a conical ring cutter mounted at one end of each sleeve. A disassembly / reassembly assembly for connecting the conical sleeves is provided on each conduit. A groove is formed on one side of the inner wall of the support frame, and a motor is mounted on the inner wall of the groove. A rotating shaft is mounted on the output end of the motor, with one end of the shaft rotatably connected to the inner wall of the support frame via a bearing seat. A first gear is fixedly fitted onto the outer wall of the rotating shaft, and a second gear is fixedly fitted onto the outer wall of each conduit; the first gear meshes with the second gear.

[0006] In a preferred embodiment of this utility model, the disassembly and assembly assembly includes a locking block, which is installed on the outer wall of the conduit. A slot is provided at the other end of the conical sleeve, and the locking block is engaged in the slot. A fixing block is installed on the outer wall of the conical sleeve, and a positioning rod is installed on one side of the fixing block. A positioning hole is provided on the locking block, and the positioning rod moves through the positioning hole. A limiting component for fixing the limiting rod is provided on the locking block. By setting the locking block, the locking block can be engaged in the slot, thereby limiting the conical sleeve.

[0007] In a preferred embodiment of this utility model, the positioning rod is adapted to the positioning hole, and the locking block is adapted to the locking groove.

[0008] In a preferred embodiment of this utility model, the limiting component includes an insert block, which is slidably connected to one side of the locking block. The outer wall of the positioning rod has a slot, and the insert block is inserted into the slot. By setting the insert block, the insert block can be inserted into the slot, thereby limiting the positioning rod.

[0009] In a preferred embodiment of this utility model, the insert block is adapted to the slot.

[0010] In a preferred embodiment of this utility model, a limiting groove is formed on one side of the card block, and a limiting slider is installed on one side of the insertion block. The limiting slider is slidably connected to the limiting groove. A limiting rod is installed on the inner wall of the limiting groove. The limiting rod moves through the limiting slider. A spring surrounds the outer wall of the limiting rod. The spring is installed between the bottom end of the limiting slider and the bottom end of the inner wall of the limiting groove. By setting the limiting rod, the limiting slider and the spring can be limited, ensuring the stability of the limiting slider when sliding and the spring when compressed.

[0011] In a preferred embodiment of this utility model, the limiting slider is adapted to the limiting groove.

[0012] In a preferred embodiment of this utility model, a groove is provided at the bottom of the inner wall of the support frame, and a collection box is provided in the groove. The collection box movably passes through the front of the support frame, and a pull plate is installed on the front of the collection box. The pull plate is snapped into the front of the support frame. Guide plates are installed on both sides of the inner wall of the collection box. By setting up the collection box, the cut consumable wire fragments can be collected uniformly, which is convenient for personnel to handle later.

[0013] Compared with the prior art, the present invention has the following advantages: This invention enables the conical sleeve and conical ring cutter to rotate during the conveying process after the consumable wire is joined. This allows the conical ring cutter to quickly and effectively remove uneven areas at the joint, ensuring a smooth joint. This solves the problem in existing technologies where, during the conveying process of the consumable wire, the hollow conical cutter directly contacts the uneven areas at the joint and simply removes the uneven areas by squeezing. The friction between the hollow conical cutter and the uneven areas is low, making it difficult for the cutter to apply sufficient and effective cutting force to the uneven parts, resulting in a slow removal process and an inability to quickly smooth the uneven areas.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figures 1 to 4 As shown, a 3D printing consumable connector includes a support frame 1, a base 2 installed at the bottom of the support frame 1, and wire tubes 3 passing through both sides of the support frame 1. The wire tubes 3 are rotatably connected to the support frame 1 through bearings. Conical sleeves 9 are fitted on the opposite ends of the two wire tubes 3. A conical ring cutter 10 is installed at one end of the conical sleeve 9. The wire tubes 3 are provided with disassembly and assembly components for connecting the conical sleeves 9. A machine groove 4 is opened on one side of the inner wall of the support frame 1. A motor 5 is installed on the inner wall of the machine groove 4. A rotating shaft 6 is installed at the output end of the motor 5. One end of the rotating shaft 6 is rotatably connected to the inner wall of the support frame 1 through a bearing seat. A gear 7 is fixedly fitted on the outer wall of the rotating shaft 6, and a gear 8 is fixedly fitted on the outer wall of the wire tubes 3. Gear 7 and gear 8 mesh.

[0019] Furthermore, the assembly and disassembly components include a locking block 11, which is installed on the outer wall of the conduit 3. The other end of the cone sleeve 9 has a locking groove 12, in which the locking block 11 is engaged. A fixing block 13 is installed on the outer wall of the cone sleeve 9, and a positioning rod 14 is installed on one side of the fixing block 13. A positioning hole 15 is provided on the locking block 11, through which the positioning rod 14 moves. A limiting component for fixing the limiting rod 20 is provided on the locking block 11.

[0020] Specifically, by setting a locking block 11, the locking block 11 can be inserted into the locking slot 12, thereby limiting the position of the cone sleeve 9.

[0021] Furthermore, the positioning rod 14 is adapted to the positioning hole 15, and the locking block 11 is adapted to the locking groove 12.

[0022] Furthermore, the limiting component includes a plug 16, which is slidably connected to one side of the locking block 11. A slot 17 is provided on the outer wall of the positioning rod 14, and the plug 16 is inserted into the slot 17.

[0023] The insertion block 16 is designed to be inserted into the slot 17, thereby limiting the positioning rod 14.

[0024] Furthermore, the insert 16 is adapted to the slot 17.

[0025] Furthermore, a limiting groove 19 is provided on one side of the card block 11, and a limiting slider 18 is installed on one side of the insert block 16. The limiting slider 18 is slidably connected to the limiting groove 19. A limiting rod 20 is installed on the inner wall of the limiting groove 19. The limiting rod 20 moves through the limiting slider 18. A spring 21 surrounds the outer wall of the limiting rod 20. The spring 21 is installed between the bottom end of the limiting slider 18 and the bottom end of the inner wall of the limiting groove 19.

[0026] The limiting rod 20 can limit the movement of the limiting slider 18 and the spring 21, ensuring the stability of the limiting slider 18 when sliding and the spring 21 when compressed.

[0027] Furthermore, the limiting slider 18 is adapted to the limiting groove 19.

[0028] Furthermore, a groove 22 is provided at the bottom of the inner wall of the support frame 1, and a collection box 23 is provided in the groove 22. The collection box 23 moves through the front of the support frame 1. A pull plate 25 is installed on the front of the collection box 23 and is snapped into the front of the support frame 1. Guide plates 24 are installed on both sides of the inner wall of the collection box 23.

[0029] The collection box 23 allows for the unified collection of excised consumable thread fragments, facilitating subsequent processing by personnel.

[0030] The implementation principle of a 3D printing filament connector is as follows: In use, two filament threads to be connected are passed through the guide tubes 3 on both sides of the support frame 1. Then, the two exposed filament threads are bonded together using a hot-melt tool. After cooling, the filaments can be conveyed. During the conveying process, the motor 5 is started, which drives the rotating shaft 6 to rotate. The rotating shaft 6 drives gear 7 to rotate, gear 7 drives gear 8 to rotate, and gear 8 drives the guide tube 3 to rotate. The guide tube 3, through the locking block 11, drives the conical sleeve 9 to rotate, and the conical sleeve 9 drives the conical ring cutter 10 to rotate. When the connection point of the filament threads is uneven, the conical ring cutter 10 effectively and quickly corrects the unevenness as it passes through the conical sleeve 9. The structure allows the conical sleeve 9 and the conical ring cutter 10 to rotate during the conveying process after the consumable wire is connected. This enables the conical ring cutter 10 to quickly and effectively remove uneven areas at the connection, ensuring a smooth connection. This solves the problem in the existing technology where, during the conveying process of the consumable wire, the hollow conical cutter directly contacts the uneven areas at the connection, simply using compression to remove the uneven areas. The hollow conical cutter has little friction with the uneven areas, making it difficult for the cutter to apply sufficient and effective cutting force to the uneven parts, resulting in a slow removal process and an inability to quickly smooth the uneven areas. When it is necessary to disassemble and maintain the tapered sleeve 9, the insert plate can be pulled directly to cause the insert plate to drive the limit slider 18 to compress the spring 21, so that the insert plate is disengaged from the slot 17 and the insert plate no longer limits the positioning rod 14. Then, the tapered sleeve 9 is pulled outward to cause the positioning rod 14 to disengage from the positioning hole 15 and the locking block 11 to disengage from the locking groove 12, thereby completing the disassembly of the tapered sleeve 9.
